Tennis-Brengle stuns erratic Serena in Auckland

Jan 4 (Reuters) - Serena Williams crashed out of the Auckland Classic after fellow American Madison Brengle pulled off a 6-4 6-7(3) 6-4 upset in a see-saw second round contest on Wednesday. Brengle was 1-4 down before the 26-year-old staged a brilliant comeback to run away with the first set against the 22-times grand slam singles champion who had constant trouble with her ball toss in the swirling wind. Williams was a set and 4-3 down when she made a comeback of her own, breaking with a delicate drop shot and unleashing a running defensive forehand to clinch the tie-breaker and force the decider. Playing her first tournament since losing to Karolina Pliskova in the semi-finals of the U.S. Open last September, Williams went neck-and-neck with 72nd ranked Brengle before losing in two hours and 13 minutes.
